    $(>/path/to/a/file)

    This isn’t exactly a variable, more a method of reading 
    files

Do not use this for reading files. This will overwrite the file in question. The correct syntax is:

    $(</path/to/a/file)

A pretty decent reference. Some of it would be easier to read if it was formatted better. ie. all the flags really don't need two lines to explain them.

"Comprehensive" is a pretty tall claim, this doesn't really seem to stand up to it.

The article doesn't make any claims to being anything near comprehensive. The author describes it as being his own bash cheat sheet, and posted it just in hopes other people would find helpful what he found helpful.

A change of submission title might be in order here.
